SASH-BAR MACHINE.

SPECIFICATION forming part of Letters Patent No. 449,130, dated March31, 1891.

Application filed December 24,1890. Serial No. 375.683. No model.)

To a whom it may concern.-

Be it known that I, WILLIAM H. NOAKES, a subject of the Queen of GreatBritain, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in a Machinefor Making Sheet-Metal Sash Bars for Use in Constructing OrnamentalGlass Windows and for other Like Purposes, of which the following is aspecification.

Sheet-metal sash-bars of the class which my machine is designed to makeare used in the construction of windows formed of small pieces of glass,plain or ornamental, wherewith designs of greater or less intricacy areformed; and the purpose of this invention is to obtain a machine wherebya sash-bar well adapted for the purposes named may be made from a stripof sheet copper, brass, or zinc economically and expeditiously and ofany required external form and shape.

I have illustrated my invention by the drawings accompanying andformingapartof this specification, wherein a machine embodying theinvention and adapted to make a sash-bar of the class described isshown; but, as will be fully understood by those familiar with the art,sash-bars of this class not of the exact form, in cross-section, as thesash-bar made by this machine can be easily made in a machine embodyingthis invention by making slight changes in certain of the parts of themachine without departing from my invention.

Figure 1 is a side elevation of the machine; Fig. 2, a front elevationof the forward end of the machine, showing the front forming-rollersrequired; Fig. 3, a front elevation of the second set of forming-rollersback of the front forming-rollers; Fig. 4, a front elevation of a hollowformer forming a part of the machine; Fig. 5, a rear elevation of suchformer; Fig. 6, a longitudinal section thereof; Fig. 7, a bottom planview of the inside form required in the former; Fig. 8, a top plan viewof such central form 5 Fig. 9, a front elevation of the rear andfinishing former-rollers of the machine; Fig. 10, a cross-section of thesashbar sheet-metal strip from which the sashbar is made in thismachine, and Fig. 11 a cross-section of a completed sash-bar.

In'the operation of this machine a strip of thin sheet metal of theproper width to make the finishing-rollers, (illustrated in Fig. 9,)

emerging therefrom a completed sash-bar of the shape illustrated incross-section in Fig. 11. The forming-rollers are driven by a wheelrigidly secured to the shaft of one of the rollers and by gearingintermeshing with a gear on the driven-shaft extending therefrom to theseveral forming-roller shafts.

Like letters refer to similar parts throughout the several viewsthereof.

X is the base of the machine.

A A are the standards of the front set of forming-rollers. B B are thestandards of the second set of forming-rollers. O is the standard of thestationary formelyand D is the standard of the last and finishingrollers of the machine. These several standards A, B, and O are allrigidly secured to the base X; but the standards D D are adjustable onsuch base X.

A A are the shafts of the front set of forming-rollers E E, which arerespectively secured rigidly on such shafts A A 6 is the face offorming-roller E, which in cross-section, has approximately the form ofthe reverse or under side of the sash-bar made in the machine, and e theface of the upper roller, which has in cross section approximatcly theform of the obverse or inside face of the central part of the sash-barmade in the machine. To avoid cutting the strip ofsheet metal from whichthe sash-bar is being made as such strip passes between the frontrollers,

the face of such front rollers can only ap proximate in cross-sectionthe form ultimately to be obtained in such sash-bar.

B 13 are the shafts of the second set of forming-rollers F F.Forming-rollers F F, respectively, are secured rigidly on the shafts B Bf is the face of formingroller F, which in cross section isapproximately (and much more nearly so than is the face 6 offormingroller E) the same as the reverse or under side of the sash-barmade in the machine, and f is the face of the upper roller F, and thisin cross-section is very nearly the form of the obverse or inside faceof the central part of the sash-bar made in the machine.

I orming-rollers F F are so adjusted in reference to the thickness ofthe sheet of metal passing between them as to force the partiallyformedsash-bar through the hollow former G and between the forming-rollers F Fand the finishing-rollers H II. The hollow former G is composed of thetwo outside pieces 1 and g and the central form or core G.

g are projecting prongs from the main body of the form G, and theseprongs g extend in between the finishing-rollers H H. The extent towhich these prongs extend into the open space between the peripheries ofthe rollers H H is determined by the thickness of the sheet metal ofwhich the sash-bar is being made, sufficient space being left around theprongs and between them and the periphery of the forming-rollers ll II.to allow the metal to pass between.

his the face of the forming-roller H, and 7t is the face of theforming-roller H, and it will be observed that the parts of these facesh h which come in contact with the sash-bar passing between them areidentical with each other in form and are of the exact'shape bf thecompleted sash-bar illustrated in Fig. 11 of the drawings and letteredI.

2'' is the strip of sheet metal (illustrated in Fig. 10) of which thesash-bar I is formed or bent up. The face 7t of forming-wheel I1 is incross-section the form of the obverse side of the sash-bar, and the faceh of forming-wheel H is in cross-section the reverse side of thesash-bar, and if it is desired to vary the two sides of the sash-bar itwill be necessary to construct the face of the forming-rollers H ll tobe identical therewith, and also the cross-section of the prongs of theinside form G must be changed.

The thickness of the sheet of metal of which the sash-bar is constructedmay be varied, and the several forming-rollers A, A 13, and 13 the twoparts g g of the inside former G, the position of the inside form G inthe hollow former G, and the rollers H H can all be adjusted tocorrespond with such thickness of metal. For the purpose of thisadjustment the following means have been provided: The several shafts AA B B and D and D of the forming-rollers revolve freely in boxes J J,respectively. These boxes J J move vertically in slot K of the severalstandards. K is a cap secured to the top of the standards A, B, and D,respectively, and L L L are set-screws extending through the cap K andagainst the journal J. By turning the setscrews L journals J may beforced upward by the metal passing between the formingrollers on theseveral shafts, and the required adjustment is thus secured. M is asetescrew in part g of the hollow former G, which can be forced downwardby turning it, thereby forcing downward the forward end of the insideform G. 11 M are screws uniting the parts 99 of the hollow former G.Such screw M fits loosely in the hollow therefor in part 9 of the formerand has a thread on cut on the upper end thereof, fitting into a threadin the hole provided therefor in part q of the former. The extent towhich the prongs q of the inside form G extend between the rollers ll 11is determined by the sliding movement of the standard D on the base X,and this sliding movement is controlled by the set-screw N, fitting intothe standard a on the base X and having a screw-thread fitting into acorresponding screw-th read 92 in standard D. A strengthening-rod I canbe inserted in the hollow I of the sash-barl,if desired, in order tostrengthen the sash-bar. An iron bar of the shape in cross-section ofthis hollow l can be run through the machine along with the sheet-metalstrip '11 by taking out the form G in the hollow former G, and in suchcase in the completed sash-bar the hollow 1 will be filled with thisbar, the sheet metal being pressed closely thereto.

I-lavin g thus described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. The combination of a hollow former consisting of two blocks havinggrooves therein adj ustably held together, whereby an adj ustable formerhaving a flaring mouth at the receiving end and a smaller mouth at thedelivery end thereof is obtained, with a form suspended at one endthereof in the hollow former near the receiving end of such hollowformer, such form extending beyond the delivery end of the hollow formerand having prongs thereon adapted to extend within ahollow space to thesides of that portion of the periphery of forming-rollers rotatabl yheld in a frame therefor, which grasp the center of the strip of sheetmetal passing through the former and between such rollers, whereby theexternal and internal shape of a strip of sheet metal forced through theadjustable hollow former is determined by such hollow former and formtherein, and the forming-rollers and prongs extending between them,substantially as described.

The combination of the hollow former G, provided with a flaring mouth oropening at one end thereof, the form G, suspended at one end thereof inthe hollow former G by ad justable screw M, the form G extending beyondthe hollow former at one end thereof and such extension provided withprongs adapted to extend into the hollow space between the periphery offorming-rollers rotatably held in a frame therefor, whereby the externaland internal shape of astrip' of sheet metal forced through the hollowformer is determined by such hollow former and form therein, and theforming-rollers and prongs extending between them, substantially asdescribed.

3. In a machine for making sheet-metal sashbars for constructingornamental glass windows, the combination of adjustable formingrollers,between which a strip of sheet metal passes, forming-rollers behind thefirst-named forming-rollers, between which also the partially-shapedsash-bar passes, a flaring hollow former through which thepartially-shaped sash-bar is forced, a form suspended within the hollowformer near the large end thereof, such form having prongs thereonextending beyond the hollow former to forming-rollers behind such form,and forming-rollers behind such suspended form between which the sashbarpasses, and by which, in combination with the prongs of the form, thecompleted external shape of the sash-bar and the internal shape of thehollow sides thereof are given thereto, substantially as described.

4. In a machine for making sheet-metal sash-bars for constructingornamental glass windows, the combination of adjustable forming-rollersbetween which a strip of sheet metal passes, adjustable forming-rollers,behind the first-named forming-rollers, between which also thepartially-shaped sash-bar passes, an adjustable hollow former throughwhich the partially-shaped sash-bar is forced, a form adj ustablycontained within the hollow former, having prongs thereon extendingtherefrom to adjustable forming-rollers behind such form, and adjustableforming-rollers behind such adjustable form, between which last-namedforming-rollers the sashbars pass and by which the completed externalshape thereof is given thereto, substantially as described.
